Plan Stability through Plan Forcing with Query Store

Intermittent performance issues due to parameter-sensitive queries are a DBA's nemesis. By the time you're notified of an issue, sometimes it's gone away...or someone else has restarted the instance or cleared the plan cache, and any data you could use is gone. Capturing the different plans for those queries can be tricky, but with Query Store it becomes very simple - the hard part is deciding what plan you like best. The Query Store feature, introduced in SQL Server 2016 and also available in Azure SQL Database, captures query performance data, and it allows you to manually force a plan for a query. In SQL Server 2017 and Azure SQL DB, the Automatic Plan Correction feature will force plans for you. Sound scary? It's not. In this session we'll explore both manual and automatic plan forcing through demos so you understand how it works, what to expect, and what to watch out for when you implement it in your environment.
